When modeling a physical phenomenon, the most informative way of visualization is video.
In this article, we will describe how to turn a sequence of images into a video clip.
This article will be useful for the beginners who want to learn more about the turbulent flow and pitfalls encountered during its modeling. We'll go through:
FlowVision 3.11.01 obtained a new connector for linking to Abaqus. The new connector calls Abaqus CSE. This connector expands possibilities of direct coupling connector and has following advantages:
Such advantages are realizing by Abaqus module: Abaqus CSE Director. But such approach has his own disadvantages:
The problem of file generation was resolved. FlowVision creating file by user request. As input data FlowVision use Abaqus project which needed for connector creating.
Analysis launching by MPM-Agent has problems with commands which are transferring to Abaqus: are separated launching of Abaqus CSE Director and separated launching of project.
Script was created for resolving this problem and making launching of Abaqus more simple. This script taking data from FlowVision project and allows launching both type of connectors: Direct coupling and Co-simulation Engine.
Script as for Windows OS, as for Linux OS is attached to this paper for using.
There are many improvements in new version of FlowVision 31001. They significantly concern to functionality of adjusting and editing of computational grid such as computational grid adaptation, parameters of boundary layer grid etc. The list of main changes in comparison with FlowVision 31001:
These and other most meaningful features are described below.
If the radiation heat flow is comparable with other heat flow, which is the main heat flow source in the problem (for example, convective heat flow), you have to use a radiation model.
The radiation heat flow can be evaluated based on temperature difference between surrounding environment and the body’s surface using the Stefan-Boltzmann's law:
The formula above represents the low for the absolutely black body (Plankian radiator). For real bodies you have to multiply the value by emissivity factor.
